Mounting structure for a printing unit for bags or the like



Aug. 22, 1967 w. w. HANSEN MOUNTING STRUCTURE FOR A PRINTING UNIT FOR BAGS OR THE LIKE Filed July 6, 1965 INVENTOR. WILLIAM W. HANSEN 4 4454 ATTORNEYS United States Patent 3,337,166 MOUNTING STRUCTURE FOR A PRINTING UNIT FOR BAGS OR THE LIKE William W. Hansen, Richmond, Calif., assignor to King Sales & Engineering Co., San Francisco, Calif. Filed July 6, 1965, Ser. No. 469,616 1 Claim. (Cl. 24816) The present invention relates to means for mounting a marking attachment such as a printing unit of a conventional character in relation to a support for an article such as a plastic bag which is to have indicia or data printed thereon, for example, a serial or identification number.

More particularly the invention" is concerned with a mounting structure which is adapt-able to varying sizes of supporting means, and by means of which also the printing unit can either be placed in upright printing position or it can be placed horizontally in position for changing of the printing die for example.

It is a general object of the invention therefore to provide an improved mounting structure for a marking uni-t or printer.

Another object of the invention is to provide a mounting structure of the above character in which the mounting structure is adaptable to a wide range of sizes of unit on which it may be mounted and which also provides for positioning of the printer either in its regular operating position or in a position where the printing unit is exposed so that the actual printing head or type can be changed.

The above and other objects of the invention are attained as described in the accompanying description of a preferred embodiment of the invention as shown in the attached drawings, in which:

FIG. 1 is a perspective view of the mounting structure showing the printer or marking unit and the bag holding unit in phantom lines.

FIG. 2 is a second perspective view of the unit, taken oppositely from FIG. 1, and showing the marking unit in its horizontal or access position where the type face or type unit is exposed for cleaning or changing or the like.

FIG. 3 is a front elevation'al view of the mounting structure, the marking unit being shown in phantom lines therein.

Referring to the drawings the mounting structure comprises a base angle 10, whose vertical flange 11 forms a foot, and whose horizontal flange 12 provides a supporting plate which has two tapped holes by means of which Allen head cap screws 15 may be employed to engage with a slotted plate 13 having a longitudinal slot 13a for most of its length and providing for adjustable connection of the mounting plate 13 to the angle 12. This mounting plate 13 is provided with a pair of tapped apertures 14 to receive the Allen head cap screws 16 which pass through slots 17 respective spaced apart base flanges or angles 18 or 19 which provide one part of a two-part mounting structure for printing unit 21 shown in phantom lines. Adjacent the rear end of the vertical flanges of the angles 18 and 19, each angle is apertu'red to pass an Allen head cap screw or pivot 22, which is pivotally received therein and has a threaded connection with a U-shaped mounted bracket 23 forming the other part of the two part mounting structure so that this bracket 23 is pivotally mounted between the two angles 18 and 19. Vertical slots 25 in the bracket 23 receive two fastening screws (not shown), to secure the marking or imprinting unit 21 therein. The two projecting flanges or plates of the U-shaped bracket 23 carry a pair of Allen head cap screws 26 which receive respective wing nuts 27, and these cap screws are adapted to be received in the respective notches 28 of the angles 18 and 19 and the wing nuts 27 may be tightened to hold the marking unit in upright or printing position, and the bottom end of the marking unit is disposed inside of the cutaway portions 31 of the horizontal flanges of the angles 18 and 19. Each of these cutaway portions 31 provides a stop 30 on the horizontal flanges for engagement by the end of the printer 21 in its horizontal or access position to limit pivoting movement thereof.

Marking unit 21 also carries upright plate 36, secured thereto by respective screws 37, and, at its top, has a cross-plate 38 upon which certain pneumatic control mechanism for the marking unit is mounted as seen in FIGS. 1 and 2. The unit also includes a mounting for a switch unit 41, having a roller actuator 42 of conventional character and carried by a plate 43 having a pair of parallel slots therein by means of which it can be adjustably mounted on supporting structure such as a bag holder or bag making machine 44 of conventional character and an angle 46, by means of clamping bolts or cap screws 47. This switch has its follower 42 adjacent a pair of conventional exit jaws 50 for a bag forming machine, and the bags when formed and projected therethrough cause the jaws to open and operate the switch so that the mark unit is caused to operate with respect to a bag by ejecting its printing head 51 (FIG. 1) against a bag on support 45.

One suitable imprinting or marking unit which can be used with this is the Mark-O-Matic attachment manufactured by Adolph Gottscho, Inc. of Hillside, NJ.

While I have shown and described a preferred embodiment of the invention, it is apparent that the invention is capable of variation and modification from the form shown so that the scope therein shall be limited only by the proper scope of the claim appended hereto.

I claim:

A mounting structure for supporting a marking unit in position with respect to a support upon which articles such as bags may be placed to be marked, said structure including a base plate having an elongated slot therein for adjustable positioning on a support, a pair of spacedapart angles mounted on said base plate for adjustment in a direction transverse to the adjusting movement of the base plate, a bracket including two parallel leg members and a connecting member therebetween pivotally mounted between the rearward end of said angles for movement between a first position wherein said leg members are parallel to said angle members and a second position wherein said leg members are perpendicular to said angle members, said leg members having means for clamping engagement with said angles in said first position of said bracket, and a stop on said angles for engagement with said connecting member in said second position of said bracket member.
